In urban environments worldwide, bulky waste—such as discarded furniture, mattresses, and appliances—poses a significant challenge for solid waste management.

In 2025, Harden Machinery Ltd. solidified its leadership in industrial shredding and solid waste resource recovery.

Harden Machinery Ltd. presents the Double Drum Windshifter DDW2000, a high-performance air separation system designed for RDF/SRF production and solid waste resource recovery. Compared with conventional single-drum windshifters, the dual-drum configuration provides higher throughput, enhanced separation performance, and increased operational efficiency for mixed solid waste processing.

In solid waste management and resource recovery, Windshifters (Air Separators) are essential for ensuring end-product purity. Utilizing aerodynamic principles, these machines separate shredded waste into fractions based on density and particle size. They are critical in processing MSW, C&D, and C&I waste to produce RDF/SRF and recover recyclables by separating light combustibles (plastic, paper) from heavy inert materials (stones, glass).

Biomass co-firing has become a proven, critical strategy for coal-fired power plants aiming to decarbonize while maintaining operational efficiency. At Harden Machinery Ltd., we specialize in high-performance industrial shredding solutions that make large-scale biomass integration technically feasible and cost-effective.

The solid waste processing industry is moving from basic recovery to large-scale, high-efficiency operations. Stricter environmental policies and increasing demand for recycled materials demand pre-treatment solutions that deliver both high volume and precise particle control. Harden Machinery Ltd. introduces the SG3000RF single-shaft shredder, engineered for industrial-scale throughput with reliable fine shredding performance.

Merry Christmas and Happy New Year!

In the growing field of waste plastic recycling and solid waste processing, recyclers face a persistent challenge: balancing high-volume throughput with precise shredding quality.

In the global push toward decarbonization, biomass co-firing has emerged as a proven, scalable solution for coal-fired power plants.
